NOTE:
Before
processing hot melt material, carefully read the material
manufacturer's Material Safety Data Sheet
(MSDS) or material
information
sheet.
Nordson
supplies only general processing instructions
and is not liable for hazards associated with or damage caused by the
use
of hot melt material.
Store
the material in dry areas at room
temperature. Keep
it in covered,
dust-protected containers.
Keep the substrate at room temperature,
dry
and free of dust and
grease.
Perform tests to determine the suitable hot melt material,
optimum operating conditions, and preliminary treatment of the substrate
for the application.
Some
substrates contain plasticizers and other ingredients which
dissipate over
time.
ln some cases, surfaces are treated with waxes,
anti-stick oils,
etc.
Without adequate pretreatment, the hot melt bond
in
these applications may be defective at the time of dispensing.
The application temperature of the hot melt material at the nozzle
is
crucial for effective bonds.
Refer to the material manufacturer's MSDS or material information sheet.
Avoid unnecessary thermal
stress.
lf
the work is interrupted, reduce the
melting temperature.
Avoid heating the hot melt material above the prescribed processing
temperature.
Higher temperatures may cause charring of the hot melt
material. This results
in
downtime. ln addition, material
may generate
dangerous
vapors at excessively high
temperatures.
Remove these
vapors by using appropriate exhaust systems.
